Solenoids????

Question

what are two specific places in everday life in which solenoids are used? how do solenoids function in each use?

Answer 1

basically a solenoid is an electromagnet switch
u use smaller voltages and currents to drive larger voltage and currents
car starter motor
starting of 3 phase motors

Answer 2

Car starters have a "throw-out" solenoid to throw the pinion gear out to engage the ring gear on the flywheel of an engine.

Electric valves in dishwashers and clothes washers control the flow of water into and out of these appliances.

A coil is a solenoid although most people think of solenoids as being hollow with a ferric slug which gets pulled into the center by the magnetic field.

Answer 3

J C has two excellent examples of solenoids in use in everyday life. A solenoid works by electromagnetism. It has an electrical coil, a magnetic core (called an "armature"), and a spring, which returns the armature to its "home" position. When an electric current is passed through the coil, the armature is sucked inside the coil; and when the current is stopped, the spring pushes the armature back out, thus converting electrical current into linear motion.

Answer 4

The main use of solenoids is reduce the use of heavy cables in electric circuits.

Answer 5

Terry H gave an incorrect answer. The other two answers are right.

Solenoids are in the electric door locks on cars, in copy machines, in computer printers...
